What Marine Sampling Holland does

Marine Sampling Holland B.V. (MSH) is a Dutch specialist provider of offshore geotechnical, geological, and environmental investigation services headquartered in Velsen-Noord, Netherlands. The company operates as a private limited company (B.V.) with 1-10 employees, delivering CPT-based soil characterisation, seabed sampling, and consultancy to enterprise clients in dredging, oil and gas, offshore wind, energy infrastructure, government, mining, and surveying sectors worldwide. Services are quoted on a project-by-project basis with no publicly disclosed pricing, executed through direct enterprise engagement and a website quotation request channel, and delivered globally from Arctic to Antarctic waters. MSH operates as part of a wider group that includes sister company Wiertsema & Partners B.V. (Tolbert, Netherlands), and claims over 40 years of accumulated specialised offshore experience.

The company's technical core is a portfolio of three proprietary Cone Penetration Test (CPT) systems: the Manta CPT, available in light (60 kN) and fully ballasted (200 kN) configurations enabling penetration up to 35+ m in water depths up to 1500 m; the Mini CPT, a lightweight system for deployment from smaller vessels allowing 10 m penetration with a 2 cm² cone; and the Push-Heat TC-CPT, a joint development with Fielax that combines a thermal conductivity probe with MSH's Mini CPT for offshore power cable and pipeline design. Real-time measurements include tip resistance, sleeve friction, cone inclination, and optionally porewater pressure, temperature, dissipation tests, T-bar tests, and seismic testing. MSH complements these with more than fifteen specialised seabed sampling tools—hydraulic, electric, high-frequency, and XL vibrocorers (hydraulic variant collects undisturbed samples within 30 seconds), gravity corers, piston corers, boxcorers, Hamon and Van Veen grabs, SoniDens sonar-based density measurement, and the Geodoff MKII drilling system—supported by hydraulic deep-sea winches with 1,000–5,000 m cable capacity for deployments at depth.

MSH operates a fully self-supporting 20 ft containerised mobile laboratory that can be shipped worldwide to conduct geotechnical and geohydrological testing on-site, alongside a licenced onshore geotechnical and geochemical laboratory jointly operated with Wiertsema & Partners. Samples are classified according to European, British (BS), or ASTM standards, and consultancy deliverables include reporting, calculations, derivatives, synthesis, and desktop studies. The firm holds ISO 9001:2015 quality management certification and VCA 2017 6.0 safety, health and environment certification for offshore operations, and is a member of the Dutch Ocean Group industry association. Sister entities CEGE Caribbean (founded 2011) and SEMASO (founded 2016) extend group reach into Caribbean geotechnical engineering and global sediment management respectively.

Core offering

Marine Sampling Holland provides offshore geotechnical, geological and environmental investigation services using Cone Penetration Testing (CPT) systems and seabed sampling equipment. Offerings include in-situ CPT testing, deep-sea sampling up to 20 m depth, laboratory testing of soil samples, and custom-tailored geotechnical consultancy for offshore infrastructure projects.

Product overview

Marine Sampling Holland (MSH) is a specialist provider of offshore geotechnical, geological, and environmental research services. The company operates a portfolio of three Cone Penetration Test (CPT) systems—Manta CPT (available in light 60 kN, partially, and fully ballasted 200 kN configurations), Mini CPT, and Push-Heat TC-CPT—complemented by over 15 specialized seabed sampling equipment including vibrocorers (Hydraulic, Electric, High Frequency, and XL variants), gravity corers, piston corers, boxcorers, grabs (Hamon, Van Veen), and SoniDens. These are supported by hydraulic deep-sea winches with 1,000–5,000 m cable capacity. MSH also operates a licenced geotechnical and geochemical laboratory capable of geotechnical and geohydrological testing, with a mobile 20 ft containerized laboratory deployable globally. Services span CPT testing, seabed sampling, and consultancy covering sand/gravel deposit analysis, pipeline/cable route studies, and environmental assessments.

• Eijkelkamp: Dutch manufacturer and service provider of soil investigation, CPT and environmental sampling equipment. Comparable to MSH on CPT tooling, soil/sediment sampling methodology and laboratory testing workflows.
• AP van den Berg: Dutch-headquartered manufacturer and operator of CPT and seabed sampling equipment for onshore and offshore geotechnical investigations. Comparable to MSH on CPT tooling, deployment systems and offshore investigation workflows.
• Royal HaskoningDHV: Large Dutch engineering consultancy with maritime and coastal practices delivering offshore foundation design, cable route studies and seabed characterization. Overlaps with MSH on the consultancy and interpretation side of geotechnical data delivery.
• HR Wallingford: UK-based independent civil engineering and environmental hydraulics research organization with capabilities in marine sediment, coastal and offshore engineering. Comparable to MSH on marine sedimentology and offshore investigation consulting.

Broad incumbents

• Boskalis: Large Dutch marine services and dredging contractor with internal geotechnical and survey capabilities for offshore wind, cable and harbor projects.
