Our heritage

Formerly known as 'Van Rietschoten & Houwens' and Imtech Marine

Jan Jacob van Rietschoten

1860

The beginning of a legacy

In 1860, sea captain Jan Jacob van Rietschoten took leave of his career at sea and established himself in Rotterdam as an independent supplier of rigging and marine equipment.

Halfgeleiders

1955

Innovation with semiconductors

Rietschoten & Houwens was one of the first to apply semiconductors on board seagoing vessels. Semiconductors enabled much faster communication and calculations than traditional analogue and mechanical systems.

ECDIS

1990

Pioneer in the development of ECDIS

To improve navigational security at sea, Van Rietschoten & Houwens developed Electronic Chart Display Information Systems (ECDIS). This system later became the standard for international maritime operations.

MV Hallaig

2012

First ever certified hybrid system

The design and installation of the first hybrid battery system for an ocean-going vessel. Scottish operator CMAL's MV Hallaig was the first ship to receive a hybrid system and acted as a benchmark for the feasibility of hybrid systems on board ships.

Collaboration Johan de Witt

2015

Key partner in crew & automation consortium for the Royal Navy

The Royal Netherlands Navy, TNO, Thales and RH Marine have presented a long-term vision of the strategic ambitions of naval operations at sea. This partnership is a platform from which many pioneering maritime innovations will follow in the coming years.

Integrated Virtualised System Architecture (IVSA)

2020

Introduction of the first marine-certified virtualised system architecture

The Integrated Virtualised System Architecture replaces traditional network architecture and improves ship connectivity, maintainability and cybersecurity. The revolutionary system has been awarded the renowned wheelmark and is expected to bring many benefits in the near future.

2050

Towards a promising future

The foundation of technological innovation laid by Van Rietschoten & Houwens is still alive and well within RH Marine. We are proud of our rich and passionate history in which we were at the cradle of many innovations that are still used in the maritime industry today.

Since our establishment in 1860, we have been at the forefront of the technological development of this sector, and we intend to remain so well into the future.
