Makai has released version 6.0 of MakaiPlan, the industry standard GIS cable route engineering software.

MakaiPlan is a tool to create and edit submarine cable routes, define cables and in-line bodies, define and adjust slack, instantly create Route Positioning Lists (RPLs) and Straight Line Diagrams (SLDs), and estimate system costs. Multiple planners and designers work interactively on cable installations with easy access to and exchange of project data.

“This MakaiPlan release represents a big leap forward in the modernization of performance and features, especially for power cables,” said Duke Hartman, VP of Business Development at Makai. “Our users tell us that the main advantages of MakaiPlan are the automation and streamlined workflow that save time and effort when planning a route. The tool is used by cable engineers, owners, and surveyors, and has a sophisticated feature set that has the benefit of continuous user feedback over the last 15 years.”

Some features in the new v6.0 release include:

  • New .NET version means faster speeds and full compatibility with Windows 7 & 8.
  • Web Map Services (WMS) feature allows users to access GIS map layers from global databases for cable route planning.
  • Arc-circles in the RPL for power cables. Unlike telecom cables, power cables have high bending stiffness and turns on the seabed follow arc-circles instead of sharp turns. MakaiPlan automatically rounds the turns and properly accounts for the cable distance.
  • Automation of cable crossings and buffer zones. Buffer zones are the corridors within which the cable must be installed. MakaiPlan generates buffer zones around cables and bodies, and clearly identifies any crossings or obstructions within this zone.
  • User-defined fields in the RPL. In addition to the fields in a standard RPL, the user can easily incorporate additional properties of interest along the route (e.g., burial depth, cable properties, geotechnical data such as soil type, etc.).
  • Save geo-referenced notes to explain planning decisions for engineers in later phases of the project (i.e., simulation or execution of the cable lay).

Makai provides a tool for each of the three primary phases of a cable project: Route Planning and Engineering (MakaiPlan), Installation Planning and Simulation (MakaiPlan Pro) and Real-time At-sea Cable Installation Control (MakaiLay). Information flows seamlessly from one product to the next, and cable projects that were planned using MakaiPlan can be directly opened with Makai’s other products, preserving the information richness of the plan (GIS layers, geo-referenced notes, etc.). Compared with having to import excel files of RPLs and SLDs from a third party planning tool, MakaiPlan provides a smooth and hassle-free transition into the simulation or installation phases of development.

MakaiPlan is the #1 cable route planning and engineering software, with over 300 licenses sold and has been used for route planning of over 400,000 kilometers of successfully installed cable worldwide.

Makai Ocean Engineering Inc. is the world’s leading provider of submarine cable planning and installation software. Established in 1973, Makai is a diversified engineering company providing naval architecture, mechanical, ocean, and software engineering products and services. Areas of expertise include ocean-based renewable energy, heat exchangers, large pipelines, underwater vehicles, submarine cable software and engineering, and general marine engineering and R&D.

SAIC chooses MakaiLay Seismic and MakaiPlan Pro Seismic to simulate and control Ocean Bottom Cable (OBC) installation and retrieval operationsSummer, 2013

3D Lay Seismic Array

Seismic cable lay installation.

SAIC has purchased two MakaiLay Seismic licenses and one MakaiPlan Pro Seismic license for use in their seismic oil and gas exploration projects. SAIC owns and operates modularized cable engines and cable installation equipment together with well trained and certified MakaiLay operators to install submarine cables worldwide. SAIC often leases vessels of opportunity in the project region with which they deploy the Ocean Bottom Cables (OBCs) or node arrays.

The growing interest in Makai’s cable installation tools by the seismic exploration community has begun to translate into software sales. SAIC’s purchase marks the third recent MakaiLay seismic customer. Makai has seen an increasing number of telecom cable installers “hopping the fence” to do seismic and power cable jobs, blurring the lines between the telecom, seismic, and submarine power cable installers. Since more than 75% of the world’s telecom cable installation fleet already uses Makai software products, some of these companies are upgrading to the seismic-specific cable installation and planning modules in order to increase their competitiveness in this growing field.

SAIC submarine cable projects will now use the latest versions of two different Makai cable software products:

  1. MakaiPlan Pro Seismic: is a simulation tool to accurately plan the installation and retrieval of Ocean Bottom Cables (OBC) in mid- and deep waters. It enables powerful and precise 3D, dynamic simulations of the cable installation and retrieval. The operator can quickly simulate an entire cable lay in advance and in his office at 25 to 50 times faster than real-time. The simulations can be used to test the feasibility of the planned lays, make equipment selection, train cable engineers, pre-lay and post-lay analysis, and create a Ship Plan for installation. A detailed analysis and simulation is valuable to best understand and plan for dynamic cable situations that occur during speed changes, starts and stops, and hydrophone body deployments.
  2. MakaiLay Seismic: will enhance the capabilities of SAIC in accurately installing and retrieving seismic arrays for the oil and gas industry. MakaiLay Seismic builds on the MakaiLay engine, but it includes additional tools specifically designed for the seismic industry to accurately install and retrieve Ocean Bottom Cables (OBC) with many in-line sensors, or node arrays in mid- and deep waters. MakaiLay Seismic is flexible enough to run on laptops and assimilate information from SAIC’s collection of cable installation equipment, including Acoustic Doppler Current Profiler (ADCP) and transponders attached to the cable, and then output vessel navigation and cable payout instructions for the operators.

Global Marine Cable Retriever

Global Marine Systems Ltd is in the process of converting six of its cable installation and repair vessels to begin using the latest Makai software technology. With the addition of GMSL to the list of customers, Makai software products are now used by every single large installer and most of the smaller telecom cable installers in the world, accounting for more than 80% of the world’s cable installation fleet.

GMSL vessels will now use the latest versions of three different Makai cable software products:

  1. The MakaiLay cable installation software.
  2. The new MakaiRepair cable retrieval and repair software (unveiled at the March, 2013 SubOptics conference in Paris).
  3. The Makailay Seismic module which will enhance the capabilities of GMSL in accurately installing and retrieving seismic arrays for the oil and gas industry.

Two of the new systems have been already delivered and the rest will be delivered and commissioned before the end of the year. A training program will be conducted in August 2013 at GMSL headquarters in the UK. In addition, GMSL has also embrace MakaiPlan as the preferred submarine route cable planning tool for their survey department.

MakaiLay is an advanced finite-segment 3D cable installation software package that enables cable installers to lay submarine cables with high placement accuracy and reliability. The software calculates and displays the surface and seafloor tension of the cable in near real-time, the layback distance of the cable, the cable slack and touchdown locations on the seafloor, to enable complete control of a cable installation process.

MakaiLay fully integrates the cable laying operations with the cable control room to adjust the cable payout speed for optimum slack/tension, the plough control room, and the helmsman DP system to modify the vessel track and speed as needed. The software can receive real-time ocean current data from Acoustic Doppler Current Profiler (ADCP) instruments to model the effect of ocean currents on the suspended cable and touchdown position. Using MakaiLay, engineers can then create a new ship plan on-the-fly to compensate for the effect of ocean currents in order to maintain a high placement accuracy of the cable on the seafloor.

The new MakaiRepair software extends the capability of Makai’s submarine cable planning and installation software suite to include at-sea cable repair and recovery operations.

MakaiLay Seismic has been specifically designed to address the new challenge faced by the seismic industry to accurately install and retrieve Ocean Bottom Cables (OBC) with many in-line sensors in mid- and deep waters.

Using MakaiLay, engineers can then create a new ship plan on-the-fly to compensate for the effect of ocean currents in order to maintain a high placement accuracy of the cable on the seafloor.

MakaiLay Seismic being used for OBC project in the Red Sea – Fall 2010

MakaiLay SeismicFairfieldNodal has acquired and is successfully using two MakaiLay Seismic software licenses to complete an oil survey in the Red Sea for Saudi Aramco. MakaiLay Seismic has been specifically designed to address the new challenge faced by the seismic industry to accurately install and retrieve Ocean Bottom Cables (OBC) in deep waters. The MakaiLay Seismic systems being used in the Red Sea project is using real-time data from acoustic transponders attached to the cable to further improve sensor placement accuracy. This is a very challenging project being conducted in water depths ranging from 30 m to 1000 m and crossing seabed slopes exceeding 55°. In addition to help placing the sensors accurately, the capabilities of MakaiLay Seismic have proven very useful during retrieval operations. By accurately monitoring cable shapes and tensions on the seabed at all times, the system has allowed retrieval with lower seabed tensions, which in turn decreases cable dragging on the seabed and minimizes cable fouling with bottom outcrops which occur very frequently in the Red Sea.

MakaiPlan Licenses Sold to Huawei- Fall 2010

The MakaiFME module provides the ability to directly import more than 150 GIS database formats into MakaiPlan. The MakaiDTM module provides users with a tool to accurately process and visualize large amounts of point data collected along an seafloor survey in order to quickly identify any potential hazards for plowing or surface lay operations.

NewMakaiLay Seismic released- Spring 2010

OBC InstallationMakaiLay Seismic is an extension of the successful cable installation software, MakaiLay, developed by Makai Ocean Engineering and currently used by most of the deep water cable installers in the world to accurately lay military arrays, telecommunication and power cables with a high degree of placement and slack/tension accuracy. MakaiLay Seismic has been specifically designed to address the new challenge faced by the seismic industry to accurately install and retrieve Ocean Bottom Cables (OBC) in deep waters. MakaiLay Seismic has the capability to use real-time data from acoustic transponders on the cable and/or real-time current measurements to further improve sensor placement accuracy and retrieval control.

MakaiLay Seismic’s 3-D cable model has been optimized for the retrieval of cables. As a result, the software can now model more accurately the cable-seabed interactions and the cable being dragged as a result of the seabed cable tension. Having an accurate knowledge of the cable conditions on the seabed at all times allows for cable retrieval with lower seabed tensions, which in turn decreases cable dragging on the seabed and helps minimize cable fouling with bottom outcrops and cable abrasion, thus providing longer array life.

MakaiLay Seismic runs on a PC under Windows 7 or XP operating system.

Laying Cable Along a Target Route – October 2000 – Hydro International

“Conventional cable-lay has been carried out by the cable ship sailing along the planned route. The cable laid in this way often deviates far from the planned route due to the effect of tidal current, etc. … By introducing ICS (Makai’s Integrated Control System), we are now able to lay cable exactly to the target route and to install bodies onto the target in spite of the complexities of current, the configuration of the seabed, and the meandering planned route. Consequently, we have been successful in reducing the possibility of cable failure and in laying a number of seismographic systems which require higher precision in deep water.”

CAF – Development Bank of Latin America and Makai Complete a Study of Seawater Air Conditioning in the CaribbeanFall, 2014

Caribbean SWAC sites

Prospective Caribbean SWAC sites

CAF – Development Bank of Latin America has identified the potential use of deep seawater air conditioning (SWAC) systems in the Caribbean. Hotels and resorts are large consumers of electrical energy in Caribbean islands, and conventional air conditioning (A/C) systems account for around 40% of the total energy consumption in such buildings. SWAC uses deep cold seawater to replace the chillers used in conventional A/C systems, greatly reducing the electrical consumption and costs.

The benefits of a SWAC system include:

  • Large energy savings approaching 90% compared to conventional A/C. The system has high value in terms of sustainability.
  • Proven technology
  • Environmentally friendly – no damage to the ocean environment or harmful emissions into the air. This system greatly reduces carbon dioxide and other airborne emissions.
  • Costs are nearly independent of future energy price increases.
  • No cooling tower water consumption.
  • Cold seawater availability for secondary applications.

CAF has financed, with co-financing from the Agence Française de Développement (AFD), a feasibility study of SWAC in four Caribbean locations: Dominican Republic, Jamaica, Guadalupe and Martinique. The ultimate goal of the study is to provide information on the economics of SWAC at these four locations, which in turn may stimulate interest and investment in SWAC development. The recently completed study was carried out by Makai Ocean Engineering Inc. with assistance from Climespace/GDF Suez Subsidiary. Makai will present the results at the first Caribbean deep seawater cooling conference, which CAF is coordinating with the National Energy Commission of Dominican Republic in Santo Domingo on Thursday, 13 November 2014. Parties interested in attending the conference may contact Helen Casanova via email at to request an official invitation.

ABOUT CAF: CAF – Development Bank of Latin America is a regional multilateral development agency that promotes a model of sustainable development in Latin America and the Caribbean. CAF has co-financed these studies with the Agence Française de Développement (AFD), a financial institution and the main implementing agency for France’s official development assistance to developing countries and overseas territories.

Makai’s OTEC Turbine and Two New Heat Exchangers Arrive at the Ocean Energy Research Center in HawaiiFall, 2014

Makai has installed two new heat exchangers and a turbine-generator, which will complete the OTEC power cycle.

Kailua-Kona, Hawai`i – Makai’s Ocean Energy Research Center (OERC) in Kona, Hawaii has received several major pieces of equipment for its Ocean Thermal Energy Conversion (OTEC) demonstration plant. Two new heat exchangers (2-megawatt thermal duty each), and a 100 kilowatt ammonia turbine-generator have arrived and are in various stages of installation and testing. To date, Makai has tested four condensers and three evaporators at the OERC, each made of either aluminum or titanium. The facility has been designed to easily swap out OTEC heat exchangers, and test as many as six simultaneously.

The Ocean Energy Research Center is an essential tool for the development and testing of candidate OTEC heat exchangers. Heat Exchangers will be the single most expensive component in a commercial offshore OTEC plant and thus optimizing their lifetime, performance, and cost are critical for OTEC’s economic success. The OERC enables engineers to rapidly design, build, and test candidate OTEC heat exchangers using a sophisticated control and instrumentation system that includes thousands of calibrated, high precision sensors. These tests yield data that are fed into Makai’s OTEC plant design software to evaluate heat exchangers for lifetime (corrosion resistance), performance (heat transfer and hydraulic efficiencies), and cost (fabrication and size/weight effects on OTEC platform), as well as to optimize the next generation of heat exchangers. Makai is in the process of scaling up a design for a novel low-cost, compact, corrosion-resistant design that may significantly reduce the capital cost of OTEC heat exchangers.

Beyond its own research efforts, Makai provides objective engineering services to domestic and international third-party OTEC developers, such as testing OTEC heat exchangers, corrosion samples, and providing OTEC plant and marine pipeline design and analysis support. The OERC is primarily dedicated to OTEC research, but includes research programs in other ocean-related areas, such as corrosion prevention and heat exchangers for other marine applications. With its continuous access to large flows of both shallow and deep seawater up to 3,000 feet deep, the OERC serves as a valuable platform for international collaboration on OTEC research and development.

Finally, Makai’s 100-kilowatt OTEC turbine has been placed on the OTEC tower while heat exchanger testing is being performed. Makai plans to connect the turbine to the OTEC system, and connect power to the local electrical grid in early-2015, followed by a dedication ceremony in mid-2015. This will mark the first time in history that closed-cycle OTEC power has been connected to a U.S. grid, and represents an important step toward commercializing this clean, constant (24/7) source of renewable energy.

ABOUT OTEC: Ocean Thermal Energy Conversion (OTEC) produces electricity from the ocean by using the temperature difference between deep cold and warm surface seawater. OTEC plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity. OTEC is a constant power source 24 hours per day and 365 days per year, clean, environmentally sustainable, and can provide huge quantities of energy.

Makai awarded $3.6M to continue work on OTEC at the Ocean Energy Research Center in HawaiiFall, 2013

Ocean Energy Research Center

Kailua-Kona, Hawai`i – Makai Ocean Engineering has received a $3.6 million contract from the Hawaii Natural Energy Institute and the Office of Naval Research for research and design on the marine renewable energy known as Ocean Thermal Energy Conversion, or OTEC. Makai will perform this work at their Ocean Energy Research Center, located in Kona, Hawaii, which is the largest OTEC research facility in the world.

OTEC holds great promise because the tropical ocean is earth’s largest solar collector. According to Dr. Joseph Huang, a senior scientist at the U.S. National Oceanic and Atmospheric Administration, “If we can use one percent of the energy [generated by OTEC] for electricity and other things, the potential is so big. It is more than 100 to 1,000 times more than the current consumption of worldwide energy. The potential is huge. There is not any other renewable energy that can compare with OTEC.”  OTEC is unique among renewables because it can provide large quantities of base load (constant) electricity. France, Korea, Japan, and China also have active OTEC development programs.

Makai will work on two initiatives to serve the ultimate goal of making commercial OTEC a reality:

  • Designing, manufacturing and testing an improved heat exchanger for OTEC, and
  • Connecting power from its OTEC plant to the electric grid on the Island of Hawaii

Because heat exchangers make up about one-third of the cost of an OTEC plant, Makai will develop designs for an OTEC heat exchanger that is high-performance, low-cost, and corrosion-resistant. The goal is a product that is essential to developers of OTEC and valuable for other industries that use marine heat exchangers.

In addition, Makai will install a 100-kilowatt turbine at the Ocean Energy Research Center to generate OTEC power onto the local grid in early 2015. This turbine will make Makai’s Ocean Energy Research Center the largest operational OTEC plant in the world, and the first closed-cycle OTEC plant ever connected to a U.S. electrical grid. By operating the OTEC plant, Makai will gain operational knowledge that will aid in the design of future utility-scale power plants.

Mist Lift DiagramMakai has received a Department of Energy, SBIR Phase I award for a conceptual design and modeling of an offshore 100MW Mist Lift Open Cycle OTEC plant to determine overall economic benefits, risks, and R&D requirements. Mist Lift is a boldly different approach to Ocean Thermal Energy Conversion process that was invented by Dr. Stuart Ridgeway in 1977. Mist Lift is a form of open cycle OTEC that does not use heat exchangers, does not have large seawater pumps and which generates power with a simple water turbine. With fewer costly components, it has the potential to be less expensive to build and operate.

Optimizing OTEC Environmental Sustainability – Fall 2009

Ocean Thermal Energy ConversionThe National Defense Center of Excellence for Research in Ocean Sciences (CEROS) has funded Makai to develop a toolset of analytical and numerical programs to be used during OTEC design that will provide sustainability feedback by effectively simulating the circulation, temperatures, and nutrients around single or multiple OTEC plants, while producing power at the lowest possible cost. The final toolset will include an OTEC plant model which will manage flows, temperatures, plant geometries, power, and will optimize the plant configuration based on cost. The OTEC plant model will receive feedback from the hydrodynamic performance predicted by an OTEC 3-D hydrodynamic plume model which will model seawater intakes, discharges, velocity, near-field mixing and turbulence, and which will, in turn, be driven by boundary conditions generated by a Regional Ocean Hydrodynamic Model (HIROM).

Conceptual SWAC Analysis for Bermuda – Fall 2009

BermudaIn August of 2009, Makai completed a Conceptual Design and Cost Study for a Seawater Air Conditioning and Bottoming Cycle Power System for Hamilton, Bermuda.

Natural Resources: University Turns to Nearby Lake for Cooling, Reduces Energy Use by 87 Percent District Energy Magazine – 2nd Quarter 2001

By W.S. Joyce, PE, Cornell University.

The Lake Source Cooling (LSC) project at Cornell University uses a renewable resource – the deep, cold waters of nearby Cayuga Lake – as a noncontact cooling source for the campus chilled water system. The $58 million project began providing 16,000 tons of cooling to 4 million sq ft, or about 40 percent, of the campus in July 2000, with an 87 percent reduction in energy use compared to conventional cooling alternatives. The overall environmental benefits included a 20 million kWh/year reduction in electricity use, reduced coal combustion, and associated reductions in CO2 emissions and acid rain precursors.

In The Drink – Cities Try Cooling off with Deep Lake Water – October 1999 – Scientific American

Cornell University has embarked on a $55 million project called Lake Source Cooling, which by mid-2000 will reduce their energy consumption for air-conditioning by 80 percent. The university’s present chilled-water system relies heavily on ozone-depleting chlorofluorocarbons, whose manufacture was banned in 1996.

Hawaii-based Makai Ocean Engineering designed the pipelines at Ithaca and Keahole Point.

Ithaca is the only site where a deep water cooling project has provoked significant, though not widespread, protest-most of it, ironically, on environmental grounds. Those problems are misconceptions, according to Ithaca College biologist John Confer. The most important aspect of the project, Confer wrote in the Ithaca Journal, “is that it would set a national example for reducing global warming.”
