Sea4D for Shipping

Sea4D for the commercial fleet.

Vessel agnostic across every size and class: container, tanker, bulk, ro-ro, cruise and ferry, offshore support and workboats, worldwide.

The Scale
80%

of global trade by volume moves by sea.

UNCTAD, Review of Maritime Transport.
The Problem Here

Operating at sea means reacting as conditions change.

Those conditions are least understood where it matters most, in the direct zone: the sea within 1,000 m of a vessel or Ocean infrastructure. Situational awareness is most critical here, and gains in efficiency, workability and safety depend on it.
SEA STATE
Routed and trimmed without measurement. Fuel, CII rating and charter performance all carry the cost.
3 to 10%
efficiency gain from forecast-based weather routing, to be verified in operation.
DNV, Energy-Efficiency Measures and Technologies, 2025.
COLLISION RISK
Managed by visual and radar watchkeeping. Close aboard in a seaway, the control that suppresses sea clutter can also suppress small targets.
52%
fewer high-severity close encounters using AI-assisted systems, across 139 container ships over 12 months.
NorthStandard P&I Club, April 2026.
POSITION INTEGRITY
Reliant on continuous GNSS (GPS). The consequence of a position error is greatest close to structures and the shore.
510%
rise in GPS jamming from the first to the third quarter of 2025
Windward, 2025.
The Answer

Inside the direct zone.

SOLAS allows the sea surface ahead of the bow to be hidden from the bridge for up to two ship lengths or 500 m. Sea4D monitors the ship's direct zone, the sea within 1,000 m of her, for small craft and objects in the water, in support of the lookout COLREG Rule 5 requires.

OPTIMAL CTS
AI course and speed advice at the edge, computed live on the unit for the bridge, to save fuel. DNV puts the efficiency gain from forecast-based weather routing at 3 to 10 per cent.
AI OBJECT ID
The contact picture through fog, spray and darkness: vessels, small craft and objects in the water, such as marine mammals or hazards, detected and tracked.
POSITION INTEGRITY
Flags when the satellite position should not be trusted and keeps positioning running in ports, terminals and strategic waterways, as an aid to the bridge.

Every record supports the operator's risk assessment under the ISM Code: measured sea state, the contacts detected and tracked, and position integrity, logged for audit, vetting and charterer assurance.

BY VESSEL CLASS

One platform for every vessel size and class.

01
CRUISE AND PASSENGER
US law requires cruise ships carrying passengers to or from US ports to integrate man-overboard detection technology to the extent it is available (CVSSA). ISO 21195 sets the performance standard. Sea4D is designed to detect and track a person in the water close aboard, in sea clutter, fog, spray and darkness, and to support the man-overboard response.
02
FERRIES AND RO-PAX
Ferries make frequent crossings in mixed traffic. Sea4D is designed to detect and track small craft out to 1.5 km in clear weather, and to keep tracking them in fog, spray and darkness, so the crew can act sooner.
03
TANKERS AND CHOKEPOINTS
GNSS jamming and spoofing are common in several straits and port approaches. Sea4D is designed to flag when the satellite position should not be trusted and to keep positioning running in ports, terminals and strategic waterways, as an aid to the bridge.
04
TUGS AND HARBOUR WORK
Sea4D is designed to give one live picture of the vessels and small craft around the tug, and to measure the sea state at the point of work. Decisions in close quarters and in marginal weather are then based on measured conditions.
05
PORT OPERATIONS AND PILOTAGE
Sea4D detects, tracks and classifies the vessels and objects in the sea within 1,000 m. It is designed to measure the sea state at the pilot boarding ground, so pilot transfers are decided on the measured sea state, with the record available for VTS and incident review.
06
READY FOR AUTONOMY
Uncrewed and reduced-crew vessels need sensing that still works in fog, spray and darkness, when cameras are limited. Sea4D supports detect and avoid with radar-first perception and position integrity, as an aid. It does not feed autonomous control.

Projected production-unit figures; to be verified in production trials.

Ports and terminals.

Pilot boarding.
Judged today from the pilot boat and the bridge. With Sea4D, the sea state is measured at the boarding position where it lies within the unit's reach.
The approach.
Watched today by vessel traffic services or a local port service, radar and AIS. With Sea4D, contacts in the unit's field of view are detected and tracked from the shore, transmitting or not.
Tugs and pilot boats.
They work close aboard among workboats and small craft, often in marginal conditions. With Sea4D, the craft around them are detected and tracked and the sea state is measured at the point of work.
Risk assessment.
Built today on incident reports and periodic traffic surveys. With Sea4D, a continuous record of traffic and conditions at the approach supports its review.

The Ports and Marine Facilities Safety Code asks harbour authorities to assess marine risks formally and reduce them so far as is reasonably practicable. Sea4D supports compliance and is not vessel traffic services equipment.

Designed with reference to
IMO CII
EU ETS
FuelEU Maritime
IMO MASS Code

Sea4D is a situational-awareness aid that supports compliance. It is not a type-approved navigation device, and it supports the navigation radar.
