Eni/Fincantieri energy collaboration, All-electric CTV, Heerema makes history, New contracts

It’s Good News Monday!

This Monday we talk about:

  1. Eni, Fincantieri in Energy Transition Collaboration

  2. Crew transfer vessel 100% battery-powered, can be recharged offshore

  3. Long-term Contracts with Petrobras for Subsea 7 PLSV Trio

  4. Heerema makes history with turbine installation from a floating vessel

  5. Sam Pan Marine Orders Up to 12 CTVs from Strategic Marine

Eni and Fincantieri signed an agreement for a partnership focused on initiatives for the energy transition. Eni is an Italian oil giant and Fincantieri is an Italian shipbuilding company - their collaboration will focus on decarbonization projects in transportation, energy, and the circular economy. The companies said: “Eni and Fincantieri have identified areas of common interest for developing synergies, including reducing the environmental impact of the maritime transport sector, producing energy from renewable sources and the circular economy”. This is the second partnership in two weeks after Aker Solutions, DeepOcean, and Solstad Offshore created an offshore renewables ‘Windstaller Alliance’ last week.

Ad Hoc Marine Designs Ltd (AHMD) revealed a new crew transfer vessel (CTV) with 100% battery power that can be recharged offshore. The ship is a 15 meter Faraday class they are calling an ‘electric personnel transfer vessel’, or ePTV. It aligns with the UK government’s vision of a maritime sector without internal combustion engines. They will be built only at AMC on the Isle of Wright in the UK. AHMD/AMC won the clean marine Department of Transportation Grant along with MJR Power, Turbulent Marine Simulations, Stirling Batteries, and ORE Catapult. We covered some of the awards in a recent Good News Monday.

AHMD sees the new concepts as more fitting with some CTVs “being stretched to the limit” by offshore wind farms that are getting farther from shore. If those developers are looking to be 100% green, it makes sense to switch from diesel to electric propulsion. The new vessels feature batteries that can be recharged as well as quickly swapped out. They can be recharged at a mothership or at the turbine, with the mothership creating its own power with wind generators. The mothership can stay in the area as a floating hotel and charging station while the ePTVs transfer crew to locations.

Subsea 7 announced an award by Petrobras for long-term contracts for Seven Waves, Seven Rio, and Seven Sun, all pipelay support vessels. The contracts are worth between $500 and $750 million all together. All contracts have a three-year period with one-year option and all vessels are expected to start in 2022 with one of each starting in Q1, Q2, and Q3.

Sleipnir installing a wind turbine blade on an offshore turbine

Heerema Marine Contractors did a demonstration project “in collaboration with Delft Offshore Turbine (DOT), a research project that focuses on reducing the cost of offshore wind energy, and Delft University of Technology (TU Delft) to collect operational data and test installation techniques.” The project is called floating offshore installation of XXL wind turbines (FOX), and includes Heerema, DOT, TU Delft, with support from the Dutch Ministry of Economic Affairs and Climate Policy and Eneco. Subcontractors included “Heerema Engineering Solutions, F&B Group, Harco Heavy Lifting, Ampelmann, Sif, and CAPE Holland.”

The RNA concept’s goal is to make it possible to install offshore wind turbines from a floating vessel without the need for a jack-up. Relative motion between the vessel’s crane and the turbine is the biggest challenge, especially during blade installation. Heerema’s guided root end positioning tool (GREPT) makes it possible. The RNA technique has been going through testing for the last two years with the vessel Sleipnir at Eneco’s Prinses Amalia offshore wind farm. They also tested DOT’s slip joint connection between the turbine and the foundation that doesn’t require grout or bolts.

Sam Pan Marine Holdings Pte Ltd, a Singapore-based company, ordered six Strat Cat 27 (SC27) crew transfer vessels (CTVs), with an option for six additional vessels, from Strategic Marine (S) Pte Ltd. Strategic Marine Group will provide commercial management services for the new ships, including marketing. The vessels are designed for offshore wind farm and renewables use, and will add to the 25 units Strategic Marine has delivered since 2010. They feature multiple hybrid propulsion options that reduce costs, noise, and vibration. They are built to reach speeds of 30 knots or more.

Smile, it’s Good News Monday! :-)
