You provide the case and requirements, we develop a fit-for-purpose excavator
Seatools is a distinguished expert in the development and manufacturing of fit-for-purpose mass flow excavators. Thanks to our strong engineering capabilities and background we develop any type of mass flow excavator for purposes that include wreck excavation, debris removal, pipe span correction, rock dump removal, seabed leveling, and pipeline or cable de-burial.
Extend the performance and applicability of your existing mass flow excavator
Seatools performs maintenance, repair, and upgrading activities on self-manufactured as well as on third-party mass flow excavation equipment. Seatools performed multiple upgrading projects that enabled clients to perform excavation operations with equipment that had originally been designed for significantly different purposes. The basic mass flow excavator is a case in point.
Save on short-term excavation jobs
Not only do we design and manufacture MFE tools, we rent out mass flow excavators too. When desired, we also provide a supervisor. Thanks to a dedicated LARS and a high level of automation, a minimum of external crew is required. This makes our equipment highly suitable for rental services and significantly reduces costs on the customer’s end.
HOW WE CREATE VALUE
Highly automated excavation operations
Thanks to our strong control engineering capabilities, Seatools is able to develop mass flow excavation equipment that features a high degree of automation. We can, for example, incorporate fully dynamic positioning capabilities with auto-track functionality. This option allows the operator to pre-program a track for the excavator, resulting in highly accurate, productive, and safe excavation operations, especially advantageous to long-distance cable de-burial and de-burial of specific objects such as subsea manifolds.
Innovative, fit-for-purpose mass flow excavators
We deliver innovative, fit-for-purpose mass flow excavators that significantly improve the economies of our customers’ operations. We achieve this by – among others – taking operational aspects into account, such as required deck space. The Carrera 4, for instance, covered only 46% of deck space compared to competing equipment, which yielded significant indirect operational cost reductions.
Short lead times in conjunction with first-time-right delivery
Our organization is set up in such a way that projects can be executed within a short time frame. Not only do we deliver equipment solutions extremely quickly, our engineering principles also ensure first-time-right delivery. This means our equipment functions as it should when first put to use.

Standardized excavation equipment
- Carrera 4 – Mass flow excavator
Multi-purpose mass flow excavator
The Carrera 4 is a multipurpose mass flow excavator, an excellent choice for trenching and excavation operations. Thanks to its dual mode capability, the tool performs across a wide range of soils. Another unique feature is its plug-and-play design: the dedicated LARS enables for fast mobilization and deployment.
• Broad applicability: multiple soil capability and adjustable trench width
• Compact design
• Plug-and-play design
Our track record is characterized by innovative and highly reliable equipment solutions

A quickly mobilized and easy-to-operate excavator ideal for remedial spot work
DEME was in the possession of a Seatools fall pipe ROV that included a mass flow excavation insert. For a particular job, however, this configuration could not be applied due to insufficient water depth. Therefore, DEME asked Seatools to design a mass flow excavator based on the existing mass flow excavation insert.
The result was a simple and cost-effective system deployed from a multi-cat vessel. This enabled DEME to complete its assignment with success.

A quickly mobilized and easy-to-operate excavator using a minimal footprint
In order to perform subsea pipeline repairs and pipeline free span corrections in the GOM, our client Oceanteam requested an easy-to-operate mass flow excavator that requires a minimum of deck space.
The result was a very compact, plug-and-play mass flow excavation system. Thanks to its elegant design, the complete spread, including power pack, takes up 20 feet only. The success of the Carrera 4 resulted in the delivery of 3 units to Oceanteam.

Unprecedented excavation power combined with fully dynamic positioning capabilities
A U.S.-based client asked Seatools to perform a conceptual design study for a mass flow excavator with 1600 HP installed power and fully dynamic positioning capabilities. The intention was to use the custom design for highly effective de-burial of lengthy pipelines at significant water depths.
Several different concepts were explored, developed, and reviewed, leading to a feasible concept that met all prescribed criteria.

Fall pipe ROV capable of performing multiple seabed preparation tasks
The Flintstone FPROV is one of the largest, most powerful, and versatile ROVs that Seatools ever built. The ROV can be equipped with a mass flow excavation insert to facilitate high-volume excavation tasks. This electrically driven insert is controlled by the main ROV control system.
Thanks to its multifunctional setup, this FPROV enables DEME to perform multiple seabed tasks using the same piece of equipment, which results in significant cost savings.
