Maritime Construction Services BV and MRTS JSC, were awarded the contract for development of the Kirinskoye Gas Condensate Field (GCF) development as part of the Sakhalin III Project for RusGazDobycha LLC. Three Infield Pipelines were installed in around 75-90m water depth. A 20” Trunkline of approximately 29km length (with 100mm concrete coating) was installed from shore to the manifold location.

The pipelay activities were performed using the PLB Resilient for the infield lines and shore approach and the PLV Timas 1201 for the deep-water export line and PLET.

Sealand Projects were appointed by DEME to support the development Marine Operations Assurance Manual for managing Crew Transfer & SIMOPS during marine works at the Hinkley Point C facility, which were scheduled to commence in Q2 2021 and extend through Q2 2023.

The focus was the assessment of transfer methodology, logistics, quayside facilities, nominated vessel interfaces and marine operational controls required to facilitate the safe and efficient transfer of crew.

A HAZID workshop was facilitated to engage key stakeholders; to highlight gaps, opportunities, risks, and areas for improvement; prior to developing the detailed engineering.

Oil Search Alaska is pursuing the Pikka Development in the north of Alaska. This requires drilling of wells, construction of facilities and infrastructure, and subsequent production operations to produce and transport crude oil.

To support the facility, a Seawater Treatment Plant is to be provided on a barge to provide water injection facilities at the facility. This barge will be floated into a graving dock and ballasted to rest on the seafloor.

Sealand coordinated the T&I activities and interfaces of the barge from Batam, Indonesia, to South Korea for integration and onward dry tow to Alaska for final wet tow into position.

The project was to perform life extension work on an existing FPSO mooring system. Through Maersk Supply Service, Sealand completed work scopes on eight of the nine mooring lines, with a primary focus on remedial work on three mooring lines.

The project included heading control of the FPSO, replacement of mooring lines, as well as installation and hook up of new mooring components.

CSV Maersk Achiever performed the offshore execution, along with two L-class anchor handling tugs used for FPSO heading control.

The Ocean Clean-up is a non-profit organisation whose aim is to develop advanced technologies to rid the world’s oceans of plastic. A key focus as part of this goal is to develop a system to commence clearing the Great Pacific Garbage Patch (GPGP), an area three times the size of France where floating plastic has accumulated.

This particular project saw the deployment of System 002 (code named Jenny) deployed between two anchor-handlers in the GPGP.

Sealand Projects completed a feasibility study on the potential to provide carbon abatement to the Cygnus platform in the Southern North Sea through electrification.

The primary focus of this study was the opportunity for collaboration with Offshore Wind Farms within the vicinity, identifying the potential partners, boundaries and constraints in electrical, technical, regulatory and commercial terms.

The Oasis Power Buoy is an innovative solution for powering Crew Transfer Vessels (CTV) used in operations and maintenance of Offshore Wind Farms.

The Power Buoy uses a direct connection to a wind turbine with subsea cables to recharge any hybrid / electric powered vessels whilst the CTV is on standby in-field.

The system can be retrofitted to existing WTG or incorporated in new designs.

Sealand provided support to Oasis Power to help progress the buoy from a feasibility study to the trial stage.

The Gravity Base Structure (GBS) c/w Meteorological Mast was installed in the Eastern Development Area in Summer 2014 for Moray East OWF.

The integrity of the mast lattice structure was compromised during installation and as a result, requires to be decommissioned at the earliest feasible opportunity. Given the weight, size (33.5m x 32.5m x 16.0m) and position of the structure, a full assessment was required to determine the options for decommissioning. Considerable stakeholder engagement was required to identify suitable reception facilities and enabling assets to transport the structure.

The Metals Company (TMC) is undertaking a comprehensive deep-sea research programme collecting polymetallic nodules from the Clarion Clipperton Zone (CCZ) in the Pacific Ocean. Successful sourcing and processing of these nodules generating almost zero solid waste could provide power for electric vehicles and other high-powered storage requirements for years to come.

Sealand, through Maersk Supply Services, have provided operational support for this research campaign, helping to facilitate the collection operations allowing time to develop an environmental basline of the proposed operating environment.
