The financial and technical consequences of an accident, or an unexpected occurrence during temporary phases involving offshore marine operations, can be devastating. This fact alone emphasises the importance of having a well-defined marine operations verification scope, a recognised technical reference, competence and experience, and quality of service.
Purpose
Our internationally recognised marine operations and warranty services provide the required independent assurance towards stakeholders and regulatory authorities that marine operations performed during temporary phases are performed safely in accordance with project and regulatory requirements.
Benefits
By applying a well-defined scope for marine operations verification, a recognised technical reference, competence and experience, we reduce the risk of something going drastically wrong significantly. Given the value of the oil and gas equipment transported and installed at sea, marine operations verification is money well spent.
Our approach
DNV offers warranty survey services for all structures, objects, vessels and equipment, systems and procedures involved in marine operations. The service covers simple coastal transportations to complex offshore installations. Our acceptance reference is the DNV Rules for Planning and Execution of Marine Operations. These rules are recognised world-wide by both the marine and offshore industries, and are commonly quoted as an industry reference for marine operations. These rules give general as well as specific requirements for planning and executing marine operations, such as:
- Load transfer operations
- Towing
- Special sea transports
- Offshore installation
- Lifting
- Sub sea operations
- Transit and positioning of mobile offshore units
- Removal of offshore structures.
Upon acceptance of design calculations, equipment procedures and plans, a marine operation declaration is issued that is widely accepted by insurers, regulatory authorities and stakeholders.
In addition, our services are supported by the following recommended practices:
- DNV RP-H101 Risk management in Marine and Subsea Operations;
- DNV RP-H102 Marine Operations during Removal of Offshore Installations.
Our staff are experienced master mariners, naval architects and structural engineers who are well-qualified and experienced to help you manage your offshore risks. The combination of site and office work is considered a key element in the quality of our service. All surveyors within DNV performing marine operations work have valid offshore certificates and are qualified through the DNV Qualification and Service Competence Scheme. These are qualified for design reviews and/or field surveys. Other specialists within related areas such as hydrodynamics, structures, foundations, pipelines, risers and moorings are available within DNV to support this activity.
Our goal is to provide you with quality verification services of marine operations that, contribute to safe and cost-effective execution.
