Staff personnel form the core of this team, which is supplemented by contract personnel in accordance with the requirement of each project. Collectively they have experience in a diverse range of fields including: Offshore Construction, Pipeline and Flexible Flow line Installation, Submarine Cable Installation, Remotely Operated Vehicle Services, Diving Services, Survey and Geotechnical Services and Maintenance & Repair Services.

Furthermore, Dolphin Marine International can provide additional services to its Clients to name but a few:

Offshore construction encompasses a wide variety of activities from pipelines and flexible flow lines, offshore terminals and fix moorings, cable laying to subsea development and installation of offshore structures. Dolphin Marine International technical consultancy and engineering fields extend from wellhead to platform or landfall.

Pipelines and Flexible Flow lines Installation
Offshore Terminal and Fix Mooring

Dolphin Marine International provides technical consultancy for a complete pipeline or flexible flow line project, from engineering to route survey through to installation, hook up and burial. Furthermore, in shallow waters it is often necessary to stabilize pipelines from the effect of tidal and wave actions. In this regard, Dolphin Marine International can provide pipeline stabilization with the use of mechanical anchors.

Single point mooring and similar systems are a practical alternative to export pipelines or loading terminals. Dolphin Marine International expertise includes installation, inspection and maintenance.

Submarine Cable Installation

Dolphin Marine International can assist a complete submarine cable project through a range of cable lay vessels, cable burial and protection equipment and cable repair systems. This capability applies to all forms of submarine cable, be it telecommunications, control or power cables.

During project execution Dolphin Marine International can provide cable route and as-laid surveys, tracking of buried cables, remote cable touchdown monitoring, cable stabilization and free-span rectification.

In addition, Dolphin Marine International can provide its expertise in cable burial and protection using underwater trenching vehicle. Solutions could be found whether the cable needs to be lay and bury or post lay and bury from landfall to offshore structures. In all, Dolphin Marine International provides the complete solution to all submarine cable projects.

Remotely Operated Vehicle Services

Increasing water depths, marginal field developments and the need to remove the human diver from the water for economic and safety reasons, have accelerate the development of the Remote Operated Vehicle. Dolphin Marine International is well placed to meet the requirement of the market, ranging from small observation vehicles to large work class ROV capable of undertaking a wide variety of tasks. Typical work tasks include:

Diving Services

Although the Oil & Gas Industry is changing rapidly and is increasingly relying on remote technology, Dolphin Marine International believes that there will always be a requirement for the human intervention offshore. Dolphin Marine International employs dedicated, highly trained dive teams with access to large and diverse amounts of equipment, to carry out diving operations around the world. Tasks undertaken include:

Dolphin Marine International can provide the standard equipment required to support diving operations in a range of water depths, from air diving spreads for relatively shallow waters works to complete saturation diving systems for working at maximum water depths.

Survey and Geotechnical Services

Survey and Geotechnical services are essential requirement for all offshore operations. Activities include:

Geotechnical investigation is a prerequisite to design, construction and installation of all offshore structures. The objective is to collect all necessary data to enable preparation of a reliable engineering study. Dolphin Marine International involvement in the offshore geotechnical investigation commenced years ago with the design, construction and operation of both submersible rotary wire line coring machine and heave compensated drilling rigs throughout the world.

Maintenance and Repair Services

The harsh marine environment and unavoidable associated marine operations makes continuous inspection, maintenance and repair essential to ensure safe and secure production. In this perspective, Dolphin Marine International can provide dedicated teams of experienced and well-trained people to cover the entire spectrum of inspection, maintenance and repair of any offshore equipment and installation. Whether it is for pipeline (EPRS, hyperbaric or atmospheric welding, tie-in, spool, free-span correction, anodes retrofit), platform (structural repair, riser, bracing), cable (splicing, unburial), offshore terminal and loading buoy (plem and flexible replacement). What ever the requirements are, Dolphin Marine International goal is to offer its expertise and experience to the Offshore Industry.
