Workboats

Workboats Solution

High Reliability, Low Emissions, Long Duty Cycles

Workboats (tugs, pilot boats, crew boats, harbour workboats) typically require long standby hours, frequent start‑stop cycles, and high thrust output. Traditional diesel solutions suffer from high fuel consumption, emissions, noise, and maintenance costs. HyMatt-Tech provides LFP battery systems for workboats, supporting series/parallel hybrid or full electric propulsion. Whether you want to add a hybrid retrofit to an existing diesel vessel or build a zero‑emission electric workboat, we offer batteries, propulsion integration, or complete vessel solutions.

What Do Workboats Need?

High reliability

Tugboats, pilot boats, and other workboats perform critical port and offshore operations. Any downtime leads to safety risks or major financial loss.

Battery systems passrigorous marine environment tests(vibration, salt‑fog, inclination). BMS with multiple protections ensures uninterrupted operation.

Continuous duty capability

Workboats often remain on standby 24/7 or operate at low load for extended periods (e.g., escort, mooring waiting). The propulsion system must deliver stable output.

LFP cells support high‑frequency charge/discharge. Smart thermal management ensures high efficiency at low load. Hybrid configurations available for seamless switching.

Safety certification

Workboats operate in complex environments (harbors, narrow channels, near shores) with crew or near critical infrastructure. Battery systems must meet class society safety standards.

DNV certification in progress . Systems designed to DNV rules (fault isolation, thermal runaway protection, redundant BMS). Full technical documentation for certification available.

Long life & low TCO

Workboat operators focus on long‑term costs. Frequent battery replacement or high maintenance directly reduces profit margins.

5,000 cycles(@80% DOD),10+ years design life . Maintenance‑free – no daily upkeep. TCO significantly lower than lead‑acid and other lithium solutions.

Technical Configuration Recommendations (Hybrid / All‑Electric)

Small pilot boat / crew boat (10–15m)

Hybrid: LanghESS‑S1 50–100 kWh + existing diesel, 30% fuel saving All‑electric: LanghESS‑S1 150–200 kWh + 100–150 kW motor, range 4–6h @15kn

Medium harbour tug (18–25m)

Hybrid: LT‑C1 500 kWh–1 MWh + twin diesel, peak bollard pull increased 15–20% All‑electric (new build): LT‑C1 1.5–2 MWh + 2×400 kW motors, range 6–8h @8kn

Large tug / icebreaker (>25m)

Hybrid: multiple LT‑C1 containers (1–2 MWh each) + multiple diesels, optimised fuel consumption Full electric rarely practical; deep hybrid recommended (diesel‑electric with battery peak shaving)

FAQs

Our most frequently asked questions

Are batteries seawater resistant?

HyMatt‑P1 and LanghESS‑S1 cabinets are salt‑spray tested, IP67 sealed, with marine‑grade corrosion‑resistant connectors.

Is charging convenient?

Use ordinary 220V shore power (slow charge) or optional DC fast charge. Small solar panels can also be added for trickle charging.

What is battery lifespan?

5,000 cycles retaining 80% capacity. One full discharge daily equals over 13 years of use.

Do I need a new charger?

If replacing lead‑acid with HyMatt‑P1 at the same voltage, the original charger may work, but we recommend a lithium‑specific charger for optimal lifespan.

Will the retrofit pass vessel inspection?

We provide complete drawings and documentation to assist with ZC or CCS approval. Successful cases exist.
