For the last decades, we have delivered on numerous worldwide projects offering a variety of highly specialised offshore installation and construction projects. We have developed and expanded our capabilities in the offshore market, evolving into a world-renowned engineering, procurement and construction (EPC) contractor. Our fully integrated EPC services encompass detailed design and verification, procurement of materials and associated services, and of course installation and commissioning services; all delivered in one complete package. 

The extensive range of offshore services we offer includes:

  • Subsea Rock Installation (SRI)
  • Pipeline shore approaches
  • Shallow water pipeline installation
  • Offshore dredging, trenching and backfilling
  • SPM (Single Point Mooring) installation
  • GBS (Gravity Based Structure) installation

Subsea Rock Installation

Our high-precision Subsea Rock Installation (SRI) activities are vital for the stabilisation and protection of offshore pipelines, cables and other installations such as GBSs (Gravity Based Structures) and offshore wind farm foundations. 

As a market leader in this industry, with more than four decades of experience, our large and modern fleet of DP flexible fallpipe vessels and side stone dumping vessels enables us to provide pre-pipelay and post-pipelay rock installation (e.g. for freespan or upheaval buckling mitigation), scour protection, seabed improvement and ballasting services for offshore structures in water depths of up to 1,500 metres.

Pipeline shore approaches

In designing and constructing the landfall area, where oil and gas pipelines approach the shore, a vast array of specialised equipment and activities are necessary. Especially as it relates to the nearshore area, Van Oord has developed a one-stop-shop concept, whereby we combine all the services we deliver into one complete package.

We benefit from a large variety of fit-for-purpose equipment that includes linear winches, multi-purpose construction vessels, dredging equipment and a shallow water pipe lay barge. This allows us to provide specialist services such as trenching and backfilling, pulling and laying of shallow water pipelines, site preparation, site re-instatement and landfall construction.

As an experienced contractor in the nearshore area, we have executed many challenging, complex projects such as the Russian landfall for the Nord Stream pipeline, several shore approaches on Sakhalin Island (Russian Far East), the Middle East, Australia and Europe.

Shallow water pipeline installation

Through its ingenuity and versatility, Van Oord’s shallow water pipe lay barge Stingray adds value to the wide array of one-stop-shop EPC services that we offer for oil and gas projects in shallow water.

Stingray is capable in handling offshore pipelines up to 60 inches in water depths up to 100 meters. Our working methods are suitable for the pulling and installation of pipelines from the shore (bottom pull), pulling works to the shore and offshore installation (pipe lay) and the installation of pipelines from an offshore vessel (float and sink). The barge is also suitable for buoy and manifold installation, hook-up, commissioning, piling and midline tie-ins. 

Offshore dredging, trenching and backfilling

Our roots as a dredging company give us a leading edge when it comes to the application of dredging techniques in the oil and gas industry.

For offshore pipelines, platforms or subsea installations, we are specialised in seabed intervention, benefiting from a large fleet of trailing suction hopper dredgers that can reach water depths of more than 100 metres. These vessels are also suitable to be equipped with specialist tools such as Mass Flow Excavation devices or ripper heads, designed for creating trenches in hard soils.

Our hoppers are therefore exceptionally adapted to the execution of challenging projects such as the Baydaratskaya Bay Crossing trenching and backfilling project in Northern Russia. For dredging assignments in greater depths, or when unique local conditions disallow the use of our conventional dredging equipment, we closely co-operate with suppliers of specialist tools to jointly address these challenges.

Besides our hoppers, we have a wide range of cutter suction dredgers, backhoe dredgers and auxiliary equipment, which enables us to provide the most effective combination of excavation and backfilling methods. We are continuously striving to enhance our techniques to be able to offer the optimal solution for every project.

SPM installation

Our track record and reputation are rapidly expanding in the area of Engineering, Procurement and Construction (EPC) contracts. This underscores our capabilities to manage and execute, in one complete package, highly complex projects that include detailed design and verification, procurement of materials and services, installation and (pre-)commissioning services.

In the Single Point Mooring (SPM) installation market, Van Oord’s credentials in EPC projects have been thoroughly validated with the execution of several prestigious projects such as the Midia Marine Terminal in Romania and the Abu Dhabi Crude Oil Pipeline (ADCOP) SPMs and subsea pipelines in the United Arab Emirates.

We offer an extensive range of specialised services that help to distinguish Van Oord as the premier one-stop-shop EPC contractor for SPM installation projects around the world. These are delivered in one complete package, with the unwavering goal of offering our clients value-added services and an innovative, reliable approach to achieving their desired outcomes, all the while aiming to achieve the perfect balance between capital and operational expenditures.

GBS installation

As one of the very few offshore contractors in the world, Van Oord has been involved, and remains involved, in numerous prestigious projects that encompass the full scope of towing and installation of Gravity Based Structures (GBSs), which may also include dredging, soil improvement, ballasting and scour protection.

Despite the limited number of GBS installations globally, we consider the fulfilment of these projects to be one of our core activities. They demand the perfect combination of the unique requirements for versatile resources, both in staff and equipment, and the specialist skills to manage complex projects that comprise a great number of critical interfaces.

We have established a comprehensive and commendable track record that includes projects as the installation of the Arkutun Dagi GBS and Molikpaq near Sakhalin Island and installation of the Malampaya CGS in The Philippines. 

Quality, Health, Safety and Environment

Management of Quality, Health, Safety and the Environment (QHSE) have the highest priority within Van Oord Offshore. We believe that QHSE issues affect – and can be affected by – all levels of our organisation.

Our pro-active approach therefore encourages active awareness of QHSE issues and compliance with QHSE rules, in order to create a ‘safety culture’ that allows us to work safely together, while providing services that meet our clients’ requirements.

To manage our operations, we have implemented a QHSE Management System which meets the requirements of the ISO 9001:2008 and ISO 14001:2004.
