The E-Pusher™ is a modular and scalable electric pusher tug.

The E-Pusher Series has three models ranging from 5,5 to 22 meters in length and a maximum depth of 0,45 to 1,35 meters resulting in a draft that is 30% less than conventional pusher tug designs. The swappable energy containers range from Stage V diesel, (Bio)gas and Hydrogen to battery solutions.

Hull and Frame
Steel frame to support all (horizontal) push forces and distributes (vertical) weights of the various components on deck.
Hull is made of Polyethyleen (PE) which provides the buoyancy and resists water forces of the vessel during sailing.

100% recyclable | fast and cheap building process by Roto moulding | lightweight |extremely tough due to the PE properties | unsinkable due to foam filling | ideal form can be made very low resistance | no anti-fouling needed

The SD Power is a state-of-the-art DP-2 Azimuth Stern Drive (ASD) Anchor-handling Tug (AHT which is a unique VARD design offshore tugboat.

The SD Power features a four engine set-up delivering up to 130 tonnes bollard pull and is equipped with a unique winch configuration system installed under the accommodation of the vessel, allowing a double drum to work both forward and aft.

The vessel is highly suitable for offshore towage, support and anchor-handling operations, as well as offshore support duties with a heavy-duty winch and aft deck. The unique DP system with External Force Module allows the SD Power to operate very accurately in close proximity of (floating) objects.

The SD Honour is a modern powerful DP-2 Azimuth Stern Drive (ASD) Anchor-handling Tug (AHT).

The vessel delivers up to 120 tonnes bollard pull and is equipped with a large accommodation, powerful Fire-fighting II classed system and large aft deck.

The SD Honour is highly suitable, equipped with two heavy duty double drum winches placed both forward and aft, for offshore towage and anchor-handling duties.

The ART 100-42 series is designed to the specific requirements for offshore FLNG (Floating Liquified Natural Gas) tanker berthing and unberthing duties, offshore support operations including emergency response, fire-fighting and personnel evacuation.

The ART 100-42 design features a double winch configuration placed both forward and aft and is equipped with the RotorTug triple propulsion system delivering up to 100 tonnes bollard pull.

The unique RotorTug propulsion configuration with three azimuth propellors enables the operator to continue to work longer in harsh weather conditions.

The Infield Support Vessel (ISV) has been specifically designed to meet the requirements from FLNG Shell Prelude

The ART 85-32W design RotorTug has evolved from the successful ART 80-32 design RotorTug, with a modified hull form to cope with higher bollard pull and increased stability during escorting and enhanced maneuvrability.

Identical to the ART 80-32 features the RotorTugs triple propulsion and double towing capacity with winches placed forward and aft. The ART 85-32 design delivers up to 85 tonnes bollard pull and holds an Escort Notation.  The Rotortug concept offers increased security for ship handling and escort towing, as well as enhanced crew safety.

The ART 80-32 design Rotortug features a 32.00 meter long vessel design with triple propulsion delivering up to 80 tonnes bollard pull.

The ART (Advanced Rotortug) has been designed to provide operators with increased maneuvrability and redundancy with the Rotortug technology, as well as providing enhanced crew safety and comfort.

The Rotortug design has been recognized by ports and industry leading companies within the mining and offshore energy sector as a risk mitigation tool at ALARP (As Low As Reasonable and Practicable).

KOTUG is the inventor of the Rotortug®, which uses a triangular propulsion configuration to provide improved vessel safety, power, efficiency and manoeuvrability. It provides total control with maximum redundancy and superior safety.

The Rotortug has been recognized by ports and energy majors as a risk mitigation tool at ALARP (As Low As Reasonable and Practicable).

KOTUG operates a variety of Azimuth Stern Drive (ASD) tugboats that support terminal and offshore floating production facilities operations.

The vessels deliver up to 70 tonnes bollard pull and are equipped with winches placed forward and aft for enhanced flexibility and workability.

KOTUG has developed and operated the first hybrid tugboat in the world. The basis for this battery hybrid Rotortug concept was a conversion of an RT 80-32 design (RT Adriaan) followed with two purpose built hybrid ART 80-32 design Rotortugs.

KOTUG is always at the forefront of innovation and environmental awareness and continues to incorporate innovative solutions in tugboat designs such as battery hybrid, cross-link mechanical, full electric, LNG and other types of reduced emission propulsion systems onboard the vessels.

KOTUG operates various tugboats which are designed to withstand the extreme cold, allowing to operate in ice-affected waters and providing towage support as well as ice-management and light ice-breaking duties.
