At Heerema, our offshore decommissioning execution philosophy is firmly based on five pillars to help customers succeed: Reputation, Capability, Predictability, Flexibility and Responsibility. Our unsurpassed track record of successfully executed, complex, and integrated Engineering, Preparations, Removal and Disposal (EPRD) projects underscores the robustness of this philosophy. We deliver peace of mind, cost-effective and complete EPRD solutions to our customers.
Heerema operates its own fleet of semi-submersible crane vessels as well as a large number of transportation barges and tugs. This provides us with access to the most suitable assets for complex offshore removal operations in the harshest of environments. The realisation of an inhouse Simulation Center and the introduction of our new SSCV Sleipnir in 2019 will further expand the offshore capabilities that we can draw on to deliver cost effective and smooth removal operations.
