What is Offshore Management in Shipping?

Offshore management in shipping refers to the management of ships that operate in offshore environments, such as the open sea, coastlines, and offshore oil and gas fields. This includes a variety of tasks and responsibilities, such as ensuring the safe and efficient operation of the ship, managing the crew and maintenance of the ship, and overseeing the transport of goods and equipment to and from offshore platforms. Offshore management also involves compliance with international and local regulations, such as those related to safety, the environment, and labor standards. The goal of offshore management is to ensure the safe, reliable, and efficient operation of ships in offshore environments, while minimizing risks and maximizing profits.

What do we call Offshore Units/Vessels?

OSM Thome can provide Technical Management for your Offshore Units/Vessels, as well as Recruit and Manage the Crew for them. Finally, we can provide you with OSERV Provisions and Catering Management.

The Floating Production Storage and Offloading (or FPSO) unit is a floating vessel (or facility) used by the offshore oil and gas industry. It is equipped with hydrocarbon processing equipment for the separation and treatment of crude oil, water and gases. An FPSO vessel is designed to receive hydrocarbons produced from its wells, nearby platforms, or subsea equipment. After processing, an FPSO stores oil or gas before offloading periodically to shuttle tankers or transmitting processed petroleum via pipelines. A vessel used only to store oil, without being processed, is referred to as a Floating Storage and Offloading (or FSO) vessel. Consequently, for gas storage the offshore unit used is called a Floating LNG Gas Storage Unit (or FSU).

The Mobile Offshore Drilling Unit (or MODU) or just “Drilling Unit” is a unit modified or designed to be used in the exploration and drilling operations of oil and gas in the sea. These Units are large industrial facilities that carry out the mission of exploring (via drilling), extracting, storing and processing oil and gas they unearth from deep below the seabed.

An Accommodation Platform is a “flotel”, which supports living quarters for offshore personnel. The Accommodation Platforms are often associated with the Oil and Gas industry, although other industries use them as well, such as the Wind Farm industry.

The Cargo Transfer Vessel is a relatively new type of Offshore Unit that transfers hydrocarbons directly from a Floating Production Storage and Offloading Unit (FPSO) to a conventional Suezmax-class tanker or VLCC. A Cargo Transfer Vessel represents a more cost-effective and faster alternative to Dynamic Positioning Shuttle Tankers (DPSTs), which until now have been vital in transferring crude oil from FPSOs to export Tankers, in difficult sea conditions.

What means Offshore Project Management?

Offshore project management refers to the management of projects that are carried out in an offshore environment, usually in the oil and gas, or renewable energy industries. This involves managing all aspects of the project, including planning, scheduling, resource allocation, budgeting, and risk management, to ensure that the project is completed on time, within budget, and to the required quality standards. Offshore project management often involves coordinating the work of teams located in different locations, including onshore and offshore locations, and working closely with stakeholders such as customers, suppliers, and regulators. The goal of offshore project management is to ensure that the project is completed successfully and delivers the desired outcomes while minimizing risk and maximizing efficiency and value.

What do we call Offshore Support Vessels (OSVs)?

OSM Thome can provide Technical Management for your Offshore Support Vessels, as well as Recruit and Manage the Crew for them. Finally, we can provide you with OSERV Provisions and Catering Management.

Anchor Handling Tug Supply (or AHTS) vessels are very powerful ships normally seen working with Offshore installations, such as a Drilling unit or even a Semi-Submersible Rig. AHTS vessels have crane-like equipment (known as “the winch”) that can be attached to the installations and then propelled forth in the water. The “anchor supply” mentioned as a part of the vessel’s name, is then allowed to be sunk into the water in order to keep the installations steady. They also provide towing assistance during tanker loading, deep-water anchor handling, and towing of threatening objects. AHTS vessels sometimes also serve as Emergency Response and Rescue Vessels (ERRVs) and as supply transports.

The Platform Supply Vessel (or PSV) is an OSV specially designed to supply oil and gas platforms at sea with logistic support. Platform Supply Vessels also transport goods, tools, equipment, and personnel to and from offshore oil and gas platforms, and other structures.

The Cable Laying Vessel is a ship designed to lay cables underwater for telecommunications, electric power transmission, or other purposes. There are two main types of cable ships: cable repair ships and cable-laying ships.

The Seismic vessel is used as a survey vessel for the purpose of mapping the sea bottom subsurface. Energy companies have traditionally utilized this data for oil and gas exploration, but as we have now entered a phase of decarbonization it is becoming more and more utilized in the renewables segment, windfarm infrastructure planning, carbon storage as well as subsurface mineral exploration. At OSM Thome we also manage Seismic support vessels being responsible for guard duties, operation bunkering (in-line re-bunkering of seismic vessels), crew changes and operational support. We also manage node handling vessels that are responsible for the deployment of sea bottom nodes.

The Multi-Purpose Supply Vessel (or MPSV) is what its name says: an offshore support vessel for multiple purposes; an MPSV can perform a range of activities including supply duties, lifting operations, ROV and survey activities, platform and SPM maintenance, diving, light well intervention and accommodation support.
